The use of Bombax species, particularly Bombax ceiba (commonly known as silk cotton tree), in the treatment of eczema is primarily justified by traditional medicine systems such as Ayurveda and certain folk practices in parts of Asia. In these traditions, various parts of the Bombax tree, including its bark and flowers, have been used for their purported anti-inflammatory, cooling, and wound-healing properties. Such uses are documented in classical Ayurvedic texts and ethnobotanical surveys, where Bombax ceiba is recommended for a range of skin ailments, including eczema, ulcers, and dermatitis.

However, scientific evidence directly supporting the use of Bombax for eczema is very limited. A few in vitro and animal studies have indicated that extracts of Bombax ceiba may possess anti-inflammatory and antioxidant activities, which could theoretically benefit inflammatory skin conditions. Yet, no robust clinical trials or human studies have confirmed its efficacy or safety specifically for eczema. As a result, the rating for evidence is low, with traditional anecdotal support greatly outweighing scientific validation. Health professionals generally recommend evidence-based therapies for eczema, and more research is needed before Bombax can be considered a scientifically validated option for this condition.
